Symptoms appear on the leaves of young plants as palegreen
to greygreen,
watersoaked
streaks
near the leaf tip and margins.
These lesions coalesce and become yellowishwhite
with wavy edges.
The whole leaf may eventually be affected, becoming whitish or greyish and then dying.
Leaf sheaths and culms of more susceptible cultivars may be attacked.
Systemic infection results in wilting, desiccation of leaves and death, particularly of young
transplanted plants.
In older plants, the leaves become yellow and then die.
In its advanced stages, the disease is difficult to distinguish from leaf blight caused by Xanthomonas
oryzae pv. oryzicola, but lesion margins are wavy rather than linear as for the former. Damage is often
associated with lepidopteran leaf rollers, leaffolders
and hispa beetles, since bacteria readily enter the
damaged tissue caused by insect infestation
